The typical 'cannon' is powerful and good against both companies and defences. Capable of firing solid and explosive shots.
The archetypical cannon was used all across the world by the mid to late 15th century. Mounted on a large wheeled chassis and featuring a longer improved barrel, the cannon is far superior to the bombards that preceded it. Able to demolish enemy walls from a greater range and able to fire troop-killing explosive shells, the cannon is rightly feared.
